Cant copy letsencrypt cert to webmin and usermin

Hi new ubuntu 14.04 and virtualmin install here

I addied domain and trying to get letsencrypt working, i can issue cert

Then i copy it to ProFTPD, Postfix, Dovecot, but when i press webmin or usermin button it says copied, but then u go back and theres still active buttons to copy it, and it dosent says its in webmin or usermin it says its used by mail and ftp only, and its loop, so cant get it working.

heres screenshoot https://gyazo.com/a41d50846d9a5308f5786f34ec362eef

Why it not copies for webmin and usermin? i did it before many times and was ok, never had this prob.

it looks like there is cert files in /etc/usermin

domain.com.cert domain.com.key

but Virtualmin dont see it

Any fix?

Thanks
